6.0 Operator's Troubleshooting guide
6.1 Envelopes jam in blade and do not exit letter opener.
Paper jamming in letter opening blade is most often due to more than one envelope feeding
into the cutting blade at once or envelope contents in the cutting area. Possible causes with
repairs are listed below:
1. Dirty feed belts-Clean as outlined in section 5.1.
2. Catch tray is full, envelopes "backing up" into blade cutting area-Empty catch tray
3. Retarder needs readjustment. Loosen lock nut on retarder adjusting screw and turn
retarder adjusting screw clockwise or counter-clockwise as needed.
4. Retarder pad worn, replace with new pad.
6.2 Machine does not run at all
1. Check that opener is plugged into an active power receptacle.
2. Examine blade cover, it should be fully engaged so as to activate its safety switch.
3. Check that the power cord is firmly inserted into the letter opener.
4. Machine may be jammed to the point of non-running. Unplug and clear jam.
